Earthquake in Kleifarvatn lake in Krýsuvík volcano

Today (30. May 2023) an earthquake took place in Krýsuvík volcano in Kleifarvatn lake. This earthquake had a magnitude of Mw3,1. I don’t know if this earthquake was felt, it is possible. This earthquake is the second earthquake in this magnitude range in last few days.

This seems to be normal earthquake activity, it doesn’t seems to be connected to any magma movement in Krýsuvík volcano. Effects of inflation in other volcanoes (Fagradalsfjall volcano) is something that might be starting to create earthquakes. This is difficult to see in the data at the moment, but that might change in next few weeks if that is happening.
